Abstract

An object of the present invention is to provide an emulsion composition that keeps smooth texture due to methyl polysiloxane, prevents the crystal precipitation of macadamia nut oil fatty acid phytosteryl to enhance formulation stability, and has a superior effect of conferring a resilient feel and emollient property. The present invention relates to an emulsion composition comprising (A) macadamia nut oil fatty acid phytosteryl, (B) methyl polysiloxane, and (C) one or more oils selected from the group consisting of glyceryl tri(2-ethylhexanoate), methylphenyl polysiloxane, cetyl ethylhexanoate, pentaerythrityl tetraethylhexanoate, and tripropylene glycol pivalate, wherein the content ratio of (A) to (C), (A):(C), is 1:3 to 1:200.

Claims

exact text as granted — not AI-modified
1 . An emulsion composition, said composition comprising:
 (A) a component of macadamia nut oil fatty acid phytosteryl,   (B) a component of methyl polysiloxane, and   (C) a component of one or more oils selected from the group consisting of glyceryl tri(2-ethylhexanoate), methylphenyl polysiloxane, cetyl ethylhexanoate, pentaerythrityl tetraethylhexanoate, and tripropylene glycol pivalate,   wherein the content ratio of (A) to (C), (A):(C), is 1:3 to 1:200, and said component of methyl polysiloxane interacts with said component of macadamia nut oil fatty acid phytosteryl to prevent said component of macadamia nut oil fatty acid phytosteryl from crystal precipitation.   
     
     
         2 . The emulsion composition according to  claim 1 , further comprising a component of (D) polyethylene glycol. 
     
     
         3 . The emulsion composition according to  claim 1 , wherein the content of (A) macadamia nut oil fatty acid phytosteryl is about 0.001-10% by mass, and the content of (B) methyl polysiloxane is about 0.1-30% by mass. 
     
     
         4 . The emulsion composition according to  claim 1 , wherein the content of the oils is about 1-30% by mass. 
     
     
         5 . An emulsion cosmetic manufacturer product comprising the emulsion composition of  claim 1 . 
     
     
         6 . The emulsion composition according to  claim 2 , wherein the content of (A) macadamia nut oil fatty acid phytosteryl is about 0.001-10% by mass, and the content of (B) methyl polysiloxane is about 0.1-30% by mass. 
     
     
         7 . The emulsion composition according to  claim 2 , wherein the content of the oils is about 1-30% by mass. 
     
     
         8 . The emulsion composition according to  claim 3 , wherein the content of the oils is about 1-30% by mass. 
     
     
         9 . The emulsion cosmetic manufacturer product of  claim 5 , further comprising a component of (D) polyethylene glycol. 
     
     
         10 . The emulsion cosmetic manufacturer product of  claim 5 , wherein the content of (A) macadamia nut oil fatty acid phytosteryl is about 0.001-10% by mass, and the content of (B) methyl polysiloxane is about 0.1-30% by mass. 
     
     
         11 . The emulsion cosmetic manufacturer product of  claim 5 , wherein the content of the oils is 1-30% by mass.
